extended battery/original back cover

I seem to remember some threads saying that you could still use the original back cover while using the extended battery. I am considering getting the extended battery but don't really want the extra thickness and was also hoping the phone would still fit in the QUBITS case that I bought.

Any comments?

The standard door goes on, but there is still a slight bulge.

It may fit in the case with the extended battery cover as is. A lot of cases allow the phone + extended battery to fit in it as is, since the extended battery doesn't really add much thickness to the device. I know nothing about your particular case though.
